IMPROVEMENT IN cuLTlvAToRs.`

Specification forming part of Letters Patent No. 72,107, dated December 10, 1867.

To all whom it may concern:

Be it known that I, (l. E. STELLER, of Chicago, in the county offGook, inthe Stateof Illinois, have'invented au Improved Gultivator; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in Which- Figure l is a perspective representation of my cultivator 5 Fig. 2, an elevation of the ceutral shovel; Fig. 3, an elevation of one ot' the runnersfwhich regulates the depth of the shovels and hoes in the ground.

The nature of my invention consists, first, in the use of slotted side frames, in which are titted the shanks of the shovels and hoes in such a manner as will permit the latter to have any desired angle relative to a line in which the cultivator is being moved, and also such apitch as may be necessary for cutting weeds and stirring the soil second, in arranging the shanks of the shovels and hoes to be moved forward and back, as the c'ase may require, in the slotted sides, for the purpose of regulating the distance of the two rows of shovels and hoes from each other, the front ends ot' the slotted sides being set nearer together than the rear ends in order to accomplish this purpose; third, in constructing a double evener, through whichthe tongue is made to pass and prevent said evener from having a swinging motion in a vertical plane, and also in the use ofinclined hanging braces for bringing the draft-line down to a suitable pointforopcrating the cultivator without making the evener too long; fourth, in arranging a guideby means of two or more holes in the rear standards, so that said guide can be set at such a height aswill suit various-sized persons who may operate the cultivator; fifth, in the construction and use of hinged runners for regulating the depth of the shovels and hoes in the ground 5 sixth,in securing verticalstaudards to the slotted frames for the double purpose of supporting the hinged runners and a central shovel, the shank ot' the latter being hung to saidstandards; seventh, the general arrangement of the cultivator, as will hereinafter be shown.

In order to give a correct understanding of my. invention, I have marked corresponding parts with similar letters, and will now give a detailed descriptiomwhich will enable others skilled inthe art to make and use my invention. .A A represent the upper and B B the lower slotted sides, arranged to support the shanks C E ofshovels Q Q and the shanks D D of hoes R lt, said shanks being arranged so as to move forward or back, or be set at any angle desired for cutting weeds or tilling the soil. This arrangement is very simple, yetimportantin regulating the position of the plows and` shovels; and as they can be loosened and fastened by means Qf set-screws Z Z and bolts put'through holes i, Src., in sides A B, no difficulty need be experienced in setting the shovels and plows to cultivate any kind of crop put out in rows, or tilling common soil. The upper part of the frame-work or sides is secured by cross-pieces M I and a guide-bar, E, the latter being used to regulate the cultivator, and canbe set high or low by means of bolts put through the hole 2 2, Fig. l.

Standards G G are made fast to the sides A B, and used both to strengthen the sides and provide means for the support ot`- the runners J W. These runners J W are made part of wood and part of metal, the latter beingcurved to run upon the ground, and the wood part J hinged to the standards G G in order th-at the runners may turn easily with the motion ofthe cultivator and conform to crooked and straight rows, as the casemay require.

The double evener L is made with a long slot, through which the tongue K is made to pass land prevent said evener from tipping over to the front or back when in use; andto secure said evener in place I puta brace, Y, overits top and a similar brace at the bottom and secure said braces by a bolt put through said; evener and the lrout cross-bar,- M. The evener L has also braces O O, inclined outward and extending down far enouglito give a suitable draft-point for the attachment ot'` whiiietrees; and to secure said braces'iu place braces P P are attached rigidly to the ends ot' the evener L and the lower end ofthe braces, thus securing strength and durability.

The central shovel, T, is represented as re moved in Fig. l, but is intended to besecured to t-he cultivator by means of the bar S bolted 'to the standards G G, and the end of shank U fitted in a socket, V, attached to cross-bar I, notches b D, Fig. 1, being out in said standards -and for the purpose set forth.`

-2. The slotted sides A A and B B, in combination with the Shanks G D E, arranged to be set at different angles and fastened by setscrews Z Z, as described. p

3. The combination of the guidebar E, arrnn ged to be raised and lowered ,with rear standards, H H, and sides A A B B, as described.

4. The combination ofstandardsfG G, hinged runners J W, and sides A A BB, as set forth. 5. The shrinks U of shovel T, arranged to fit in a socket, V, and bar S, in combination with standards G G and cross-bar I, as and for the purpose set forth.

G. The double evener L, arranged substantially as set forth.

7. The double evcnejr L, in combination with braces O O and P- P, with or without braces Y, substantially as set forth.
